作者研究了基于分子束外延生长的InGaAs量子点的可调谐分布反馈（DFB）激光器。采用垂直于脊波导的横向增益耦合二元叠加光栅制作了两段可调谐DFB激光器。已经实现了高达40 dB的侧模抑制比。调谐范围覆盖30纳米。
The authors have investigated tunable distributed feedback (DFB) lasers based on InGaAs quantum dots grown by molecular beam epitaxy. Two-section tunable DFB lasers were fabricated by patterning laterally gain coupling binary superimposed gratings perpendicular to the ridge waveguide. Side-mode suppression ratios of up to 40 dB have been achieved. The tuning range covers 30 nm.
